calcium supplements even if you have high blood pressure, provided:
•
Kidney function is normal
• You are not having high blood calcium levels

Vitamin D3 deficiency should definitely be treated because:
• It helps calcium absorption
• It may support vascular health
• Severe deficiency can worsen fatigue and musculoskeletal pain
Calcium does not directly increase blood pressure when taken in recommended doses.
